    Connection anchor with a glass pattern for the draft zone.
    The invention relates to a connecting anchor, in particular for anchoring in the pressure or pressure generated in the concrete by load stresses. draw zone consisting of an anchor rod and a glass cartridge that can be destroyed by the anchor rod and is filled with a curable resin and quartz grains.
    For heavy-duty attachments in concrete, such a connecting anchor system is known from EP 0 867 624 B1, wherein a connecting anchor consisting of an anchor rod that has several cone sections, which is widened towards the end of the anchor rod and can be anchored by means of a specimen mass in a borehole of a mounting substrate. The conical widenings of the anchor rods offer a good mixing of the mortar and a constant load-bearing capacity of the connecting anchor, even when cracks form in the concrete.
    Another such connecting anchor is known from EP 0 967 402 B1, wherein an anchor rod for a receiving bore filled with a specimen mass has a shank which has a connection area and an anchoring area with several conically-arranged conical widening and narrowings arranged axially one behind the other.
    The multi-component mortar is introduced into the borehole by means of a special glass pattern. The components for the specimen mass are accommodated in the glass cartridge such that one chamber contains a resin component with filler material, e.g. quartz sand, and a second chamber contains a hardener component, usually in powder form or in liquid form. The glass pattern is destroyed by turning and breaking an anchor rod. By turning the anchor rod, the components resin, glass splinters, hardener and further filler material are mixed, so that a resulting composite mass is evenly distributed between the wall of the borehole and the anchor rod.
    There where the stresses caused by the shape and the size of the component act on the concrete, so-called pressure resp. draw zones, depending on whether there is a pressure or tensile load in the relevant component. Drilling holes can widen in the tensile zone in particular by forming cracks in the concrete, whereby the mortar mass also widenes in mutual connection with the concrete. Here, an axial shift of this type of anchor rod can be followed by spreading in the cured composite mass, the cone sections sliding in the narrowed area of the mortar outer layer, so that the anchor rod again makes a positive connection with the composite mass and the load of the anchor rod remains guaranteed. For a post-spreading it is necessary for the cone surface of the anchor rod to become completely detached from the composite mass, but without releasing along the connecting surface, i.e. the plane between the composite mass and the concrete.
    A ratio of the connecting surface to the conical surface that ensures release is described in EP 0 867 624 B1. This anchor rod has a typical ratio of connecting surface to the cone surface between 3 and 4.5. The cone sections have a cone angle between 10 ° and 20 °.
    An important ratio with regard to the load-bearing capacity of the anchor rod is the value of the ratio of borehole gap surface, which is obtained from the radial distance from the borehole to the anchor rod, the annular gap, to the bolt cross section of the anchor rod. A value of the ratio of bore-hole gap to the bolt cross-section between 0.3 and 0.5 is known from EP 0 867 624 B1. A high load-bearing capacity is achieved by a small ring gap.
    The basic component of suitable specie masses consists of a solid-setting resin, usually an epoxy resin or an acrylic resin. To achieve increased solidity, the resin components are mixed with inert fillers, e.g., quartz sand, silicates or steel balls of a suitable size. The use of quartz sand as a filler material enables a cured composite with a high hardness that cannot be achieved with a pure two-component mortar without filler material. Quartz sand as a filler material also prevents the typical shrinkage during hardening of the resin, which when cracked in the concrete leads to a reduced spreading capacity of the entire connecting anchor and therefore to a lower bearing load of the anchor rod in the concrete. It is therefore decisive in curing the composite mass how much fill material is present in the glass cartridge. A low content allows a more viscous composite mass, but cannot reach the strength of the surrounding concrete to the same extent.
    A specimen mass that can be pressed into a borehole by hand is known from DE 3 226 602 A1. The specimen mass comprises quartz as a preferred filler material with a grain size of about 0.1 - 0.6 mm, resp. 0.1 - 0.25 mm with a filling of 50 - 80% in the two-component mass. A screening process with the corresponding screen size is carried out and the screened quartz sand with a statistical distribution of different grain sizes is supplied to the specimen mass. For borehole sizes from M6 to M16, quartz grains in the lower fill range for anchor rods with a maximum ring gap of 1 mm have proven to be sound. For drill holes larger than M16, in particular with ring gaps of approx. 1-2 mm. quartz grains in the upper grain range have proven to be sound.
    A two-component mass for fixing anchor rods with quartz sand as filling material is described in US 6 583 259 B1, wherein the quartz grains have an average size of 1.2-1.8 mm.
    DE 36 38 750 A1 describes a reaction set with a multi-chamber pattern for an adhesive anchoring of fastening elements with a filler content in the resin component of 40% - 45%, with examples, depending on the total composition, indicating a percentage of grain sizes in the sizes of 0 , 5 -1.8 mm or 1.2 -1.8 mm.
    In DE 4 315 788 A1 another composition is described with a part of binder and 1 - 6 parts of filler material, wherein for a glass pattern size smaller than M16, quartz grain g roots of 0.8 - 2 mm are used and for glass patterns that are larger are then M16, quartz grains with a size of 2-6 mm are used.
    DE 10 2004 035 567 A1 describes another two-component mortar with a radically polymerizable resin, fillers, further conventional mortar components and a separately applied hardener component. The resin component contains a mixture of hydroxyalkyl (meth) acrylate and an acatacetoxyalkyl (meth) acrylate. The fillers consist for a small part of fumed silica as the main component of quartz sand with a certain percentage of an average grain size of 400 µm or less than 50 µm. For the former values are 20% resp. 23% and for the latter, individual values such as 26, 29, 37 and 50% are given, which refer to the total mass.
    Furthermore, DE 4131457 A1 describes a pattern for the chemical fastening technique, which describes quartz sand grains with grain sizes of 0.5 to 3 mm, whereby pattern sizes smaller than M16 are selected for this. For patterns larger than M20, grain sizes with 3 to 6 mm are indicated.
    A disadvantage is sorting the grain sizes into just a single fraction. With this it is only possible to a limited extent to indicate a concrete composition of the sizes of the quartz grains and to keep the weight contents of the fillers in the composite mass constant. Neither does the exact state of the quartz grains used with regard to particular grain sizes for certain borehole sizes be established in the prior art. With an ever-changing quartz grain content of a not exactly known size, also due to different sieving results and with the simple indication of an average grain size, no constant fill weight in the composite mass and thus no constant hardness of each specimen mixture is guaranteed. This deviating strength can result in reduced bearing loads for fixed anchor rods with small ring gaps, especially in the loading zones of the concrete, such as the tensile and pressure zone. Although the resin components used in the prior art exhibit a high degree of solidity in the cured state, they harden very slowly due to the fluctuating temperature and humidity values. In particular, methyl (meth) acrylates, such as resin components, have the disadvantage that they have a strong irritating effect in the first case of direct skin contact and secondly do not cure directly in the air under the influence of oxygen. By screwing the anchor rod into the borehole, surplus composite mass comes out of the annular gap and forms a droplet, the so-called "overflow", which does not cure and therefore does not allow the fitter to check the hardening of the composite mass.
    SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a connecting anchor comprising an anchor rod having a glass pattern, the fast-curing composite mass ensuring a controlled mass distribution of quartz as a filling material, very high bearing loads, also for small ring gaps, both in the pressure zone and in the pressure zone. draw zone of the concrete.
    According to the invention, said object is achieved in a connecting anchor of the type mentioned in the preamble by a connecting anchor with an anchor rod and a glass pattern that can be destroyed by the anchor rod and which is filled with a curable resin and quartz grains as filling material, the the quartz grains containing the glass pattern are present in the curable resin in a controlled mass distribution of the quartz grains, the quartz grains being subdivided into two fractions into coarse quartz grains having a size of 1200 - 1800 µm with a mass percentage of 75 - 50% of the total mass of the quartz grains and fine quartz grains with a size of 120-250 µm with a mass percentage of 25 - 50% of the total mass of the quartz grains. A preferred percentage distribution of the quartz grain sizes here is independent of the diameter of the glass pattern and identical for all pattern sizes.
    It is herein provided in a preferred manner that the component of fine quartz grains is, for its part, again subdivided into two fractions of quartz grains of a smaller size of 125-180 µm with a mass percentage of 12.5-25% of the total mass of the quartz grains, and quartz grains with an average size of 180-250 µm with a mass percentage of 12.5 - 25% of the total mass of the quartz grains.
    As a result, considerably smaller ring gaps of up to 1 mm for pressure zone patterns and even up to 0.5 mm for tensile zone patterns can be chosen - compared to the prior art. This again entails a better distribution and composition of the composite mass and components, the latter before curing, so that this process improves, becomes more uniform and is accelerated. Furthermore, the shrinkage as a result of the smaller substance of the composite mass in gaps is smaller, so that a higher connecting force is created.
    The quartz grains, which are smaller than the prior art, as filler material of the finer grain fraction, provide an improved firmness of the cured specimen mass.
    Furthermore, it helps to ensure that the coarser grain components, when the anchor rod is screwed in, rub against the wall of the borehole, thereby cleaning them and thus increasing the connection thereto, as well as decreasing their size, which in turn contributes to improving the connecting force of the mass.
    In yet another preferred embodiment of the invention, a vinyl ester resin is used as a resin component in the glass cartridge. By means of a hardener in powder form or liquid form in the cured state, this hardener has the properties of a duroplastic plastic with high strength and chemical durability. The mass distribution of the quartz grains controlled in accordance with the invention, in particular in vinyl ester, additionally achieves a bonding strength similar to that of epoxy resins, but with even more application advantages. With a curing time of 20 to 60 minutes, vinyl ester shows a clearly shorter curing time than comparable epoxy resins, which must cure up to 24 hours. It is also possible to use it in wet boreholes and at outside temperatures below 0 ° C, in which the vinyl ester, in contrast to epoxy resin, hardens pressure and tensile. In comparison with methyl acrylate resins, vinyl ester resins cure evenly independently of the atmosphere, which means that the curing process can also be controlled from the outside, which is not possible with methyl acrylate, since this remains liquid as an "overflow" on the surface due to the oxygen content, so that nothing can be explained about the deeper hardening. Although vinyl ester resins contain styrene that is harmful to health, the emission values for vinyl ester resins are far below the test values when mounting glass cartridges. In contrast, methyl acrylates are harmful when they come into contact with the skin.
    The compound mass that is produced has an inert filler content of a mass percentage of 70 - 85%, and is achieved by the defined division of the quartz grains into coarse, fine and very fine grain sizes both in the drawing zone and in the pressure zone of the concrete. high bearing loads. This higher content of inert fillers compared to the prior art ensures that a composite mass is created with the compressive strength of high-strength concrete.
    In order to allow post-spreading of anchor rods in the tension zone, the anchor rod is provided in a preferred embodiment with several cone sections with a coating of PTFE or nickel, the cone angles of which are 8 ° -10 ° or 22 ° -25 °. It has been found to be particularly effective that the anchor rod in the anchored state has a ratio of connecting surface to conical surface between 2.5 and 2.9. The preferred embodiment also allows for smaller ring gaps, with a preferred value of the ratio of borehole gap to the cross section of the bolt being between 0.12 and 0.25.
    In a particularly preferred embodiment, provision is made for connecting anchors according to one of the preceding claims to be characterized in that the anchor rod has an internal thread for receiving a screw at one end intended for fixing an object. In this way a particularly stable fastening can be ensured, in particular for the draw zone, whereby screws of the usual size between M10 and M20 can be used.
    Variable length screws can also be used depending on the requirements and dimensions of the components to be attached.
    Further advantages and features of the invention are apparent from the claims and from the description below, in which a preferred embodiment of the invention is explained in detail with reference to the drawings. In the drawing: Fig. 1 shows a first illustration of an anchor rod according to the invention; Fig. 2 shows a second image of an anchor rod; Fig. 3 shows a third image of an anchor rod according to the invention according to EP 0 697 530 B1; Fig. 4 is a fourth illustration of an anchor rod with an internal thread; Fig. 5 shows a comparison of the annular gap surfaces that arise; Fig. 6 is a diagrammatic representation of the glass cartridge according to the invention in longitudinal section; Fig. 7 is a schematic cross-sectional view of the glass cartridge according to the invention.
    Figures 1 to 3 show three preferred embodiments of an anchor rod belonging to a connecting anchor 1. The anchor rod 1 in Fig. 1 is a threaded rod made of a suitable type of steel, wherein the anchor rod 1 is made perpendicular to a length of an endless threaded rod perpendicular to the axis thereof is brought to the desired length and a point is made from the end thereof with an angle of 90 °.
    The fixing base 2 of concrete is shown schematically and indicates the borehole for the connecting anchor. The anchor rod 1 comprises in the upper third part a notch 3, which is marked with a marking, to which the anchor rod 1 is slid into the borehole, the part of the threaded rod above the marking, an external thread 4, serving for the attachment of an object .
    The anchor rod 1 of Fig. 2 has an external screw thread 4 for fixing an object at the upper end, with a smooth cylindrical section 5 connecting to the external screw thread 4, the length of which allows an adjustment to the depth, in which the forces which acting on the anchor rod 1 can be introduced into the mounting base. A conically tapered shank 6 leads to three cone sections 7. The cone sections 7 narrow towards the shank 6 towards the lower end of the anchor rod and each run through a steep conical section into the respective adjacent cone section 7. The cone sections 7 are formed by a cone angle 8 which, in the preferred embodiment in Fig. 2, is 22 °. The anchor rod 1 has three uniform cone sections, with the exception of the lower cone section 7, which has a point instead of its steep conical section. The cone sections 7 arranged one behind the other on their cone faces 9 are treated in such a way that after the insertion of the anchor rod 1 into a composite mass a lower coefficient of friction is provided. For this reason, the cone portions 7 on their cone surfaces 4 are each provided with a cover layer, which in the preferred embodiment consists of polytetrafluoroethylene (PTFE) or nickel.
    In yet another exemplary embodiment, which is not shown here, an anchor rod 1, as shown in Fig. 2, can also comprise four cone sections 7, the cone angle here also being 22 °.
    FIG. 3 shows another image of an anchor rod 1, wherein this type of anchor rod 1 is already known per se from EP 0 697 530 B1. The anchor rod 1 again has an external thread 4 in the upper fourth part for attaching an object. This is followed by a cylindrical shank 10, which ends in the lower third of the anchor rod 1 into an external screw thread 11, which is screwed inside a special end nut 12. This end nut 12 is characterized by an area extending from its rear end to conically widened at its free end and a profiling 13 arranged on the outside thereof. This profiling 13 is realized as a V-shaped groove which runs helically around the end nut 12. In this example, the composite mass penetrates into the grooves of the end nut 12 and further grips the conical area of the end nut. Furthermore, the anchor rod 1 has a cone angle 8 of 10 °. The anchor rod 1 in fig. 3 also has, in comparison with the anchor rod 1 in fig. 2, a special cover layer consisting of nickel or PTFE.
    Fig. 4 shows a further embodiment of an anchor rod 1 according to the invention, wherein the anchor rod 1 has almost the same properties as the anchor rod 1 described in Fig. 2. At an end intended for attaching an object, of an external screw thread 4 an internal screw thread 4a (drawn with broken lines) formed for use with a screw. The internal thread 4a is generally formed in the interior of the anchor rod up to the end of the cylindrical portion 5 so as to accommodate the length of a screw until the desired attachment is guaranteed. The diameter of the inner thread 4a is adapted to the diameter of the anchor rod 1 that surrounds it, preferably inner threads 4a with a size of M10 to M20 are arranged. In principle, the embodiments of an anchor rod 1 according to Fig. 1 and Fig. 3 can also have such inner screw threads 4a.
    FIG. 5 shows an overview of possible ring gaps 14 between the connecting anchor and a mounting base, e.g. concrete. In example a) in Fig. 5 a ring slit 14 is shown, as it would be formed, for example, by the anchor rod of Fig. 1, and this shows a ring slit width of 1 mm. Example b) in Fig. 5 shows a ring gap 14 with smaller dimensions, in the example of the anchor rods 1 of Fig. 2 or 3, ring gap widths between 0.5 and 1 mm are also possible. A ring gap for mounting in the pressure zone is approximately 1 mm for corresponding anchor rod sizes from M8 - M36. In the drawing zone of the concrete a ring gap is achieved for sizes of M10 - M16 of 0.5 mm and for sizes of M20 - M24 of 1 mm. The annular gap formed by the annular gap is crucial for an important value, which expresses how the annular gap faces the cross-section of the anchor rod 1, the bolt cross-section and which makes it possible to say something about the strength of the anchor rod in the borehole. The ratio of borehole gap face to the cross section of the bolt can assume values between 0.12 and 0.25 here. At lower values of this ratio, the surrounding composite mass must have increased strength. A reduced ring gap results in a smaller shrinkage of the composite mass in the borehole and therefore a stronger connecting force between the wall of the borehole and the anchor rod.
    FIG. 6 shows a glass pattern 15 for a curing multi-component mass based on a radical curing resin 16, in this concrete example a vinyl ester resin. The glass cartridge 15 consists of an outer cartridge 17 and a cartridge 18 located in the outer cartridge 17. In the inner cartridge 18 there is a hardener in powder or liquid form. The resin 16 vinyl ester with fillers is introduced into the outer cartridge 17, the fillers being represented in the preferred embodiment by quartz grains in a specific mass distribution (see Fig. 7 for this).
    The glass cartridge 15 is inserted into a borehole, then destroyed by an impact of one of the anchor rods described in Figs. 1 to 3, and thus the components contained in the glass cartridge 15 are activated. By rotating the anchor rod 1 during the impact a good mixing of the components (resin 16, quartz grains, hardener and glass splinters) is ensured, which in turn promotes a better solidity of the cured mass. By mixing the components glass-resin-quartz grains and the hardener powder, a composite mass is formed with a high content of inert fillers with a mass percentage of approximately 70 to 85%, which is achieved by a controlled mass distribution of the quartz grains. The composite mass that results from this achieves the compressive strength of high-strength concrete 2.
    FIG. 7 shows the glass cartridge 15 in cross-section of the axis A-A (see also FIG. 5). The controlled mass distribution of the quartz grains is hereby schematically illustrated and clarifies the distribution of the quartz grains into three fractions, consisting of coarse quartz grains 19a, fine quartz grains 19b and very fine quartz grains 19c. The coarse quartz grains 19a with a size of 1200 µm - 1800 µm are present in a preferred embodiment depending on the diameter of the cartridge in a proportional mass percentage of 75% - 50%, the remaining mass percentage of 12.5% -25% consists of fine quartz grains 19b with a size of 180 µm - 250 µm and very fine quartz grains 19c with a size of 125 µm - 180 µm. The mass percentages here relate to the physical total mass of the quartz grains. Here, the fine quartz grains 19b and the very fine quartz grains 19c are present in equal parts. In an exemplary embodiment for the specific quartz distribution for an arbitrary glass pattern 15, the following applies:
    These grain sizes for the coarse quartz grains 19a, fine quartz grains 19b and very fine quartz grains 19c apply to glass patterns with the dimensions M8 - M30 and are present in the glass pattern 15 in an identical distribution. The coarse quartz grains 19a ensure that the composite mass is mixed by rotating the anchor rod 1 in the borehole for further grinding of the wall of the borehole. The original size thereof hereby becomes smaller when the anchor rod is screwed in. The fine quartz grains 19b, as well as the very fine quartz grains, serve as filler material between the coarse quartz grains 19a, whereby the composite mass is greatly strengthened.
    By subdividing this controlled mass distribution into a division of the quartz grains into three fractions of coarse 19a, fine 19b and very fine quartz grains 19c, it is made possible to fix anchor rods 1 according to the invention in an efficient manner with relatively small ring gaps 14 and with a high solidity of the cured composite. This also prevents the typical shrinkage during curing of the resin, which, when cracks are formed in the concrete 2, leads to a reduced spreading capacity of the entire connecting anchor and therefore to a lower bearing load of the connecting anchor 1 in the concrete 2. Due to the distribution of the quartz grains in different grain sizes and the associated small distance between the quartz grains, a thickness of the resin layer between the quartz grains resulting from the mixing with the resin component is also small, so that a considerably stronger composite layer is obtained. Due to the mass distribution controlled according to the invention, even with small ring gaps (see also Fig. 2) very high pressure loads are achieved both in the pressure zone and in the drawing zone of the concrete 2.
